HASP-LOCK.

Specification of Letters Patent.

Application filed has 1, 1913. Serial in 782,454.

To all. whom it mag concern: Y i

Be it known that I, Ocrro S. MURPHY,

citizen of the United States, residingat.

Peoria, in the county of Peoria and State of Illinois, have invented certainnewand use? ful Improvements in Hasp-Locks, of which the following is a specification.

My, invention relates to improvements in hasp locks, the principal object being to provide a lock of that character which cannot be picked or. tampered with to effectan opening, and which looks itself automati-- cally. i x a To the accomplishment of the foregoing and such other objects as may hereinafter .appear, my; invention consists in the construction, combination and arrangement. of

parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof and which illustrate a preferred embodiment ofmy invention, it being understood howeverthat various changes may be made inpractice within the scope of the claims without digressing from my inventive idea.

In the drawings :-Figure 1 represents a perspective view of a device constructed according to myinvention inuse as a latch; Fig. 2 is a plan view of thelocking portion of the device'in a locking position, the cover being removed; Fig. 3 is a similar view showing the devlce in an unlocked posltlon; Fig. 4 1s. a perspective VlQW'Of one of the tumblers; Fig. 5 is-a front View of the bolt; 1 Fig. 6 is a rear view of the bolt, and, Flg. 7

is a plan view of the compartment or chamber formed in the hasp for recelving the va-. r1ous operating parts of the lock. a

Referring now to the drawings the nu-n meral 1 designates the shank or hasp which is secured to staple 2 and has a body portion 3 having the-slotted or apertured lug or ear 4 extending therefromand adapted to be hooked or secured on the lug or hooko,

. as indicated in Fig. 1, so that the device may a form of a rectangularchamber or compartbe used asa latch. The lug or hook 5 is the means, with. which the; lock itself engages.

The body portion ,3 of the hasp isin the ment 6, having the cover 7, which is provided with the aperture 8 and aslot 9to receive the barrel 0! key cylinder 10, the lower end of which is reduced and rotatably 3 mounted in the aperture 11. This body por tion is provided near its front end with the elongated slot or opening 12, which is adapted to receive the locking lug or hook 5. The guiding and guarding flange or abutment 13 is provided adjacent the aperture 12 and extends from the lower side of the body to a position in line with the middle part of saidopening or aperture 12. The pins, lugs.

or extensions let and 15 are provided in an intermediate portion of said chamber or compartment and form means for guiding the movementof the bolt into and out of engagement with the locking lug or hook. Extending inward from the. opposite side edge of the chamber or compartment is the guiding arm or member 16 which is spaced from the bottom as shown, and beneath which is provided the extended guiding lug or rib 17.

Patented Sept. 22, 1914. a

In the lower corner of said chamber or compartment is provided the extended pin 18. ;As stated hereinbefore.

the various operating means are adaptedto be positioned in said chamber or compartment and include the bolt 19 and the tumblers, and the key barrel or cylinder 10..

The bolt 19 is formed in two parts as illustrated, the body portion 20 and the toe or looking portion 21 which has secured thereon the pin or stud shaft 22 by means of which said toe 0r locking member. is pivotally secured to said body portion or member 20. a 1

l The body portion or member 20 is of peculiar and irregular shape, having its front face flat with the exception of the extendlng supporting flange 23, the lower face 24: of

. which is beveled or rounded, as shown, this supporting flangeterminating short of the rear edge ofthe body member. The. lower portion of the body member is provided with a depending lug or extension 25, the

inner side of which merges into a recess 26,

one sidewall27 of said recess being beveled and the other side 28 being curved and merging into the straight bottom edge 29of said bottom member, The bottom portion of said body member 20 terminates on the extended lug 30, the front edge of said body portion or member 20 extending upwardly therefrom in the form of the curve 31, the

initial portion of said side or edge being straight as at 32, to provide the bearing or abutment portion. The upper edge of said front. portion is below the top edge of the main part of thebody portion to provide room for the spring 33, which is secured to said portion and end of which bears'on the toe or extension 21. The rear side of said body member or portion 20 is provided in its main portion with the ex tended groove or recess 34, in which is adapted to be positioned the guiding rib or lug 17 so as to hold the bolt in its proper position'while moving from its locked to its unlocked position. The forward portion is reduced as at 35, to provide room to receive the toe or extension 21, part'of which is reduced as at 36 so that the combined'thickness of the reduced portion of the, body member and toe member ofthe bolt are substantially equal to the thickness of the body member of the bolt. By reducing the portion of the toe or extension the shoulder'or abutment is provided which is positioned inengagement with the front edge 32 of the body portion. The underside of the toe or extension is' cut away to provide the recessed portion 37, the forward extremity of the toe- 38 being innline with the bottom straight edge 29 of the body member. The forward portion of the bottom side of saidtoe or extension 21 is beveled as at 39, and the front thereof is inclined, as at 40 to receive theiend of the spring 33 when said toe or extension is moved on its pivot by the engagement of the beveled surface 41 of the locking lug or bolt. The straight bottom edge 29 normally rests on and is guided by the pin, lug or extension 14 and the flange or abutment 13. The pin, lug or extension 15 ispositioned immediately above the flat upper edge 42 of said toe or extension 21 proper position during its movement.

and engages the top portion of the shoulder e or abutment 35, which is provided byreducing the front portion of said body member 20 so as to prevent said locking member being projected too far by means of' the spring 43 which is secured to the extended pin'lS and bears against the rear edge of the body member 20, as shown. The guiding arm or member 16 is positioned so "as to engage the flat front face of the body mem ber 20 of the bolt so as to hold it in its The bolt proper is held normally in its locked position by means of the spring 43, as has been described, and which is prevented from being moved to an unlockedposition by means of tumblers 44. These tumpurpose.

blers are of a peculiar shape and'are'pivotally mounted on the extended pin or shaft 22,'the aperture 45 being provided for that Each tumbler is provided with "the two rear extensions 46 and 47, spaced apart as shown, to provide a recess oropenmg 48, wh1ch 1n the unlocked position as shown in Fig. 3 is entered by the guiding arm or member 16. The upper extension 46 of each tumbler is longer thanthe lower extension 47, and has the cut out portion 49 providingthe bearing toe 50 and the lock- 1 01 shoulder stood that in a locked position as shown in Fig. 2, the locking shoulder or abutment is m engagement with the arm or member 16.

The lower edge of each tumbler is rounded or concaved as at The spring 53 is secured to the lower portion of eachftumbler and curved to the front end thereof with its curved: flange 23, as shown in F igs; '2; and 3, whereby each tumbler is normally held 1n extremity 54 engaging on the beveled or,

position to prevent the retraction of the;

belt, that is'wh'en thelockingishoulder or abutment 51 is in engagement'with the end of the "arm or-memb'er 16. -It is therefore obvious that the bolt'cannot be retracted' untilthe-tumblers are releasedfrom engagement with the armor member 16 to permit the entrance of said arm or member 16 into the slot or opening 48 in the tumblers as they move rearwardly. g

The key 55 is the opening means having the lugs and recesses thereon formed to operate the tumblers-and the bolt. The key 1 first engages the convexed under "surface 52 of the tumblers,llifting them and moving them on their pivots 22 until-the locking 1 shoulder or abutment 51 is free from the end of arm or member 16. At this time theoperating lug on the key engages the rear wall '27- of the recess 26 and upon-further rotalock may be engaged withvthe hook or lug 5 merely by positioningrthe same the openlng and using suiiicient force to cause said toe 21 to turn it on its pivot 22 against 'VVhat I claim is the tension of said spring 33 until the toe is lifted high enough to permitthe passage of said lug 5, when said toe 21 willbe forced into the hook by means of spring 33 andthe hasp will be locked. a
